DAYTON, Ohio (AP) — Ohio lawmakers are pushing U.S. Department of Labor Secretary Thomas Perez to speed up the timetable for determining whether to restore the full pensions of about 20,000 Delphi salaried retirees.

In a letter to Perez on Tuesday, a contingent of Democrats led by Sen. Sherrod Brown called on the secretary to help accelerate the process of making a final determination for the Delphi retirees, including about 5,000 Ohioans.

Salaried employees who retired from the auto parts maker lost most of their pensions when the government bailed out General Motors. They’ve been waiting nearly five years for a decision from the Pension Benefit Guaranty Corporation about whether to restore those benefits in line with Delphi’s union retirees.

The Dayton Daily News ( ) reports that other Democratic senators also signed the letter.
